• B. Carbon
• C. Sulfur
• D. Oxygen

Answer 1

The correct option is A

Hydrogen

Explanation for correct option

(A)

Acids

• Acids contain ${\mathrm{H}}^{+}$ ion as cation.
• The cation present in acids is ${\mathrm{H}}^{+}$, this suggests that acids produce hydrogen ions, ${\mathrm{H}}^{+}$, in solution, which is responsible for their acidic properties.
• Examples of acids are Hydrochloric acid$\left(\mathrm{HCl}\right)$, Nitric acid$\left({\mathrm{HNO}}_3\right)$, and Sulfuric acid $\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$.

The correct option is (A). The element common to all acids is Hydrogen.
